Advanced competence in intensive care unit: expectations, role ambiguity between physicians and nurses in intensive care units. Multi - method survey.

Background And Aim: The roles of physicians and nurses have undergone profound changes in recent years, becoming more complex and creating, at times, overlapping competencies with consequent negative repercussions in terms of problems related to autonomy and inter-professional collaboration. The study aims to detect the opinions of intensive care physicians and nurses with respect to their skills and role expectations.

Method: The study was conducted in two phases.

Resonantly Interacting Fermi-Fermi Mixture of ^{161}Dy and ^{40}K.

We report on the realization of a Fermi-Fermi mixture of ultracold atoms that combines mass imbalance, tunability, and collisional stability. In an optically trapped sample of ^{161}Dy and ^{40}K, we identify a broad Feshbach resonance centered at a magnetic field of 217 G. Hydrodynamic expansion profiles in the resonant interaction regime reveal a bimodal behavior resulting from mass imbalance.

Accurate Determination of the Dynamical Polarizability of Dysprosium.

We report a measurement of the dynamical polarizability of dysprosium atoms in their electronic ground state at the optical wavelength of 1064 nm, which is of particular interest for laser trapping experiments. Our method is based on collective oscillations in an optical dipole trap, and reaches unprecedented accuracy and precision by comparison with an alkali atom (potassium) as a reference species. We obtain values of 184.
